To all'whom t may concern. Be it known thatl, ROY P. -WILmMs,

'a citizen of 'the United States, residing at Pasadena, in the county of- Los Angeles and State of California, have invented a new and useful Spray-Nozzle, of which the following is a specification.

My invention relates tos ray nozzles. In the practical utilization' of water in connection with gardening, it is desirable to provide means whereby the Water can be evenly distributed over considerable areas,v

and in which both the ineness of the spray and the area sprayed can be readily controlled.

The principal object of my invention is.

to provide, such a spll'ay nozzle. Sometimes such a spray nozzle may be used in connection with a line of flexible hose, one or more of these nozzles bein connected into the hose and being move rom place to place as desired. At other times'the spray nozzles are permanently located, being connected to underground systems of piping, so that it is simply necessary to turn the water pressure on when it'i needed.

A furtherl object of my invention is to provide a lspray nozzle whichmay be used both with flexible hose and with underground systems of piping.

In such a spray nozzle there is some likelihood of dirt or waste matter accumulating in the inside of the nozzle, and a further object of my invention is to provide a spray nozzle in which the working parts may be readily removed through the top whenever it is necessary for the purpose of cleaning. It is further desirable 1n such a spray nozzle to provide means by which the nozzle can be adjusted, such means being preferably permanently securedin the nozzle itself, and it is a further object ofv my invention to provide means for this purose. v p Further objects and advantages will be made evident hereinafter, or will be evident to one skilled in the art upon an inspection of the accompanying drawing, and a Vperusal of the following specification.

-In the form of my invention illustrated in the drawing; Figure 1 is an elevation of a hose nozzle adapted for use with a line of flexible hose, and provided with an integral adjusting stem, the larger part of the nozzle being shown in section for the purpose are secured on the side Specification of Letters lfateiit. --Patentetl 1.6, 191.?5. fnppnoauon fue; :une sa, isis. semina-'samp y 22, and an upwardly extending branch v23,

a Washer 25 being provided a cap 24 an for 'closing' the branch 21, the branch f 22 having an inwardly extendin thread 26 and awasher `27, the thread 26 ein adapted to receive the end of a standar garden hose. In a similar manner the vcap 24 may be removed and the interiorly threaded end of a garden hos'e may be .secured so that a number o f body members be secured in series if desired.

plug 13, and/an adjusting thereon, 11 may for the purpose of holding the upwardly extending branch 23 in a .vertical position asthe flexible hose is moved about. The body member 12 is'secured by means of a thread 31 to the exterior of the branch 23, this body member having lan interiorly threaded cavity therethrough. A series of helical ooves 33 are cut in the walls of the cavity 32, these grooves being similarly inclined and tapering gradually in sectional area as they ascend. The grooves 33 terminate at a point 34 near the top of the body member 12. A cap 35 is threaded into the top of the cavityA 32 being provided with small holes 36 for the reception of a Spanner wrench, an

putlet opening 37l being centrally formed i 100 32 extending; upwardly l this cavity 4l terminating I 'cover the of the grooves 33. The walls -between the ports 43 are sufficiently wide to completely ooves 33 when theA plug 13 is turned to t e' closed position. Y

The'adjusting means illustrated vat 14 consists of an lu wardly extendingv stem 44 a kuur ed headl 45,. this-stem 4'4 exn i lpwardly through the outlet opening 37. square head may 'be substituted for the knurled head if'desired, so that a wrench can fbe' applied for the purpose of turning the .plug 13. Ay standard pipe fitting may be substituted for the body member 12, this pipe fitting' being'secured in a i line of pipe buried in the ground, the top l of the body member 12 bein also buried so that the top thereof 'is a ittle below the' surface of the ground. vWhen so used, the method of construction illustrated in Fig. 4 is preferable'to the method illustrated in fn Fig. 4 the adjusting -means in the plug .13 consists of a project1on 50 having arectangular slot 51 cut therein. When 1t lis desired to adjust the plug 13 in the body member 12 in the form s own 1n Fig. 4, it; Yis

vnecessary to insert a wrench or screw driver Y 32 and into-the cavity 41 inside the plug 13.

If the plug 13 is in the o en position, the ports 32 register with the ower portion of the grooves 33 and water is supplied to the lower portion of these grooves. This water entering the grooves at a certain velocity, is rapidly accelerated due to the reduction in the sectional area of the grooves, and finally emerges at the point 34, just above the top of the plug 13, at a considerably increased -velocity. As the grooves 33 are inclined,

the water enters the space between 'the top of the plug 13 andthe cap 35 in a tangential direction, setting up a rapidly whirling vortex of water between the top of' the plug 13 and the cap 35. As water lis added to this vortex through the grooves 33 it overiiows through the outlet opening 37 and is thrown o' spirally in all directions around the spray nozzle. By adjusting the plug 13 up and down in the cavity 32, the size of the port opening at 34 may be increased or diminished, and the velocity of the water entering the space above the plug 113 may be4 increased or diminished. If the opening 34 is ver large, the water will enter this spacel ata s ow rate of speed, and the quantity of while the area spra ed-will be small. If t water thrown the nozzle will be largle,

e opening 34 is Agra ually reduced, the eiective length oftheA grooves -33 is increased,

and thewater lowin tlirou h these grooves 1.) -is greatly' accelera and t e speed of the vortex is large, con uently a fine spray will be thrown over a arge area. VIn addition to the adjustment of the area and fineness of spray, by the up and down adjustment ofthe plug 13, aninstantaneous and. convenient adjustment is provided b the ports 43. In adjusting the opening 3 it is necessary to'turn'the plug 18 one or more revolutions to produce ap reciable eect. The amount of water flowing through the ports 33 can, however, be regulated without changing the effective length of the grooves v33 by turning the plug 13. so that the ports 43 onlypartially regllster with the grooves 33-` Itis thus possib e by a partial turn of the plug 13 to-wholly or partially shut olf the flow of water, this partial turn of the plug 13 making very little difference in the effective length of the grooves 33 and the. size of the opening 34.
